Grade D: Preliminary / Theoretical Evidence
Evaluation of methodological rigor, population reach, and evidence alignment.
- Design Match
- Randomized controlled trial
- Risk of Bias
- Low
- Consistency
- Consistent
Strongest recorded design is a randomized controlled trial, drawn from 3 recorded studies, 3 in people. No disagreement is recorded across them.
How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials
